IPC: H02J7/00
Filed: 2001-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a charge control device capable of always detecting only a charging current in the charge control of a battery.  <P>SOLUTION: This device is configured to make only the charging current flow in a current detecting circuit 5 by taking out output power from between a charging current detecting resistor 3 and an FET 4. This configuration enables only the charging current to be always detected, because, even when an operation is performed at the side of an electronic device unit during the charge of the battery 1, the then operating current does not flow in the current detecting circuit 5. Also, when power is supplied from only the battery 1 without using an external power supply 2, both terminals of the resistor 3 are short- circuited. As a result, power loss by the resistor 3 can be nullified, thereby avoiding the shortening of the battery life.  <P>COPYRIGHT: (C)2003,JPO
